Definitions

  • the invention is based on an electric hand tool according to the preamble of claim 1.
  • cloth bags, paper sacks or boxes are used to capture the grinding dust, which are pushed by means of a protruding inlet nozzle on a formed on the machine housing dust ejector, which encloses a dust ejection opening provided in the machine housing.
  • the paper bags and cloth bags are designed as disposable units to be disposed of together with the collected dust
  • the boxes have a dust collecting chamber which can be emptied after opening the box for repeated use of the dust collecting container.
  • the inlet nozzle opens into the dust collecting chamber and the dust collecting chamber communicates with an exhaust port which is preceded by a dust filter.
  • a known electric hand tool (EP 1340 591 A1 ) is closed with a hinged lid dust collection box as an attachable to the machine housing and removable from the machine housing housing component which is shaped so that it seamlessly connects to the machine housing and molded onto the machine housing handle part and forms an organic overall shape with machine housing and handle ,
  • a dust filter is arranged in the dust collection box.
  • the lid closes a box opening in the dust collection box which is directly opposite the dust injection opening of the stacking box. Through the box opening, the dust collection box can be emptied and the dust filter changed when the cover is pivoted off.
  • a Staubauslassstutzen which is formed at the end for connection to a dust collecting canister.
  • the Staubsammelkanister has cylindrical shape and has a support frame and a pushed onto the support frame dust bag.
  • a tubular handle is formed on the machine housing, which forms a discharge pipe for the grinding dust.
  • a suction hose of a suction device is attached on the free end of the handle.
  • a Staubausblasstutzen In a known hand tool machine with dust extraction ( DE 198 31 383 A1 ) is formed on the machine housing a Staubausblasstutzen.
  • a self-supporting dust box is detachably attached to the dust outlet.
  • the dust box has a dust collection box, a molded on the dust collection box, opening in the dust box Einblasstutzen and a dust collection box on the top closing lid with a dust filter attached to the lid.
  • the dust box is on with the Einblasstutzen Dust-tight pushed the Staubausblasstutzen the machine housing and locked releasably on the machine housing. For dust removal, the dust box is removed after loosening the latch of the Staubausblasstutzen, lifted the lid with it attached dust filter from the dust collection box and distributed the dust collection box.
  • a dust collecting container for an electric hand grinder as a box with a retracted, integrated inlet nozzle and a dust collecting chamber arranged above the inlet nozzle.
  • the dust collecting chamber is closed with a removable lid having an exhaust port and carrying a dust filter attached to the drain port.
  • the inlet nozzle is pushed onto the dust ejector nozzle formed on the machine housing, whereby a dust collector compact design is achieved with a short overall length, which does not bother when working with the hand grinder and conveniently removed for emptying the dust ejection nozzle of the machine and then pushed back.
  • To empty the dust collection chamber remove the cover with the dust filter attached.
  • the electric hand tool according to the invention with the features of claim 1 has the advantage that the fact that the dust collection box is an integral part of the machine housing, a separate housing for the dust collection container saved and thus a significant cost reduction in the production of electric power tool is achieved.
  • there is an improved and simplified handling of the machine since the dust collection container for emptying no longer separated from the machine housing, so dismantled or removed, but only the lid needs to be removed from the dust collection box. As a result, shortened working hours can be achieved in particular in electric hand tool machines with a high dust accumulation.
  • the in Fig. 1 As an exemplary embodiment of a general electric hand tool machine in side view eccentric grinder shown has a machine housing 11, at least one formed in the machine housing 11 Staubausschö réelle 12 and a dust collector attached to the latter 13, wherein a fan arranged in the machine housing 11 sucks in grinding dust from the surface of a machined workpiece and on the Dust ejection opening 12 in the dust collecting container 13 a blows.
  • the blower is driven by an electric drive motor, which also drives the sanding plate 14 projecting on the machine housing 11.
  • a possible structure of the eccentric grinder is in the US 5 018 314 shown and described in detail.
  • the dust collection container 13 has a dust collection box, hereinafter referred to collect box 15, and a collection box 15 final lid 16.
  • the lid 16 is provided with an exhaust port 17 to which a dust filter 18 is preset.
  • the dust filter 18 is attached to the inside of the lid 16 and is removed when opening the header box 15 by removing the lid 16 from the collecting box 15.
  • the collecting box 15 is formed integrally with the machine housing 11 and is designed together with the machine housing 11 as a plastic injection-molded part. He has in the embodiment of Fig. 1 Cuboid shape with two open, opposite sides, of which the first open side attaches to the machine housing 11 and covers the dust ejection opening 12 and the second open side is closed with the lid 16.
  • the two open sides are two of the cross-sectional larger longitudinal sides of the collecting tank 15th
  • the collecting box 15 again has a cuboid shape with two open sides, of which the first open side is one of the cross-sectional larger longitudinal sides of the collecting tank 15 and the second open side is the upper (in working position of the machine housing 11).
  • Fig. 2 ) or lower ( Fig. 3 ) is cross-section smaller end face of the collecting tank 15. While the first open, cross-sectional larger longitudinal side of the integrally formed with the machine housing 11 header tank 15 on the machine housing 11, the dust ejection opening 12 overlapping, attaches, the second open, cross-sectionally smaller end face of the header tank 15 is covered by the cover 16.
  • the cover 16 In the dust collecting container 13 according to FIGS.
  • the lid 16 is again provided with the exhaust port 17 and the dust filter 18 is secured to the lid 16.
  • the exhaust port 17 disposed in the lid 16 opposite, upper end wall of the header tank 15 and the dust filter 18 is mounted in the collecting box 15.
